Abstract

Detecting and characterising vehicles is one of the purposes of embedded systems used in intelligent environments. An analysis of a vehicle characteristics can reveal inappropriate or dangerous behaviour. This detection makes it possible to sanction or notify emergency services to take early and practical actions. Vehicle detection and characterisation systems employ complex sensors such as video cameras, especially in urban environments. These sensors provide high precision and performance, although the price and computational requirements are proportional to their accuracy. These sensors offer high accuracy, but the price and computational requirements are directly proportional to their performance. This article introduces a system based on modular devices that is economical and has a low computational cost. These devices use ultrasonic sensors to detect the speed and length of vehicles. The measurement accuracy is improved through the collaboration of the device modules. The experiments were performed using multiple modules oriented to different angles. This module is coupled with another specifically designed to detect distance using previous modules speed and length data. The collaboration between different modules reduces the speed relative error ranges from 1 to 5, depending on the angle configuration used in the modules., Comment: 17 pages

Abstract

[EN] The management of people and vehicles mobility is an aspect of continuous study due to its contribution to pollution. Traffic light control determines the queues that can form at crossroads. Usually, this control is not adapted to the existing traffi at a specific time since the adaptation implies knowing the pedestrians and vehicles circulating at all times. This article proposes using modular intelligent devices that allow vehicles to be detected and access times to the intersection to be changed depending on the circumstances. A simulation has been carried out generating loads in MatLab and simulating the control with Simulink. A traffic light cycle with fixed times has been simulated and compared with cycles with varying service times depending on a load of pedestrians and vehicles. In the article, the Op and Sat indicators are proposed to measure the optimisation of the control algorithm on the crossing state. Using these indicators, it has been shown that it is possible to optimise the waiting time by 50%, almost independently of the traffic load in the best case., [ES] La gestión de la movilidad de personas y vehículos es un aspecto de continuo estudio debido a la relevancia que tiene en la contribución a la polución. El control de los semáforos determina las colas que en los cruces se pueden formar. Habitualmente este control no está adaptado al tráfico existente en un momento concreto, dado que la adaptación implica conocer los peatones y vehículos que se encuentran circulando en cada momento. Para resolver este problema, en el artículo se propone el uso de unos dispositivos inteligentes modulares que permiten detectar los vehículos y cambiar los tiempos de acceso al cruce dependiendo de las circunstancias. Para validar el sistema se ha realizado una simulación generando cargas en MatLab y simulando el control con Simulink. Se ha simulado un ciclo de semáforo con tiempos fijos y se ha comparado con ciclos de tiempos variables en función de la carga de peatones y de vehículos. En el artículo se proponen los indicadores Op y Sat como método de medición de la optimización del algoritmo de control sobre el estado del cruce. Por medio de dichos indicadores se ha comprobado que en el mejor de los casos es posible optimizar en un 50 % el tiempo de espera de forma casi independiente de la carga de tráfico., Ministerio de Ciencia e Innovación de España Proyecto MICINN: CICYT PRECON-I4: Sistemas informáticos predecibles y confiables para la Industria 4.0 TIN2017-86520-C3-1-R

27. Assessing the Impact of Continuous Evaluation Strategies: Tradeoff between Student Performance and Instructor Effort

Author

Poza-Lujan, Jose-Luis, Calafate, Carlos T., Posadas-Yagüe, Juan-Luis, and Cano, Juan-Carlos

Abstract

Current opinion on undergraduate studies has led to a reformulation of teaching methodologies to base them not just on learning, but also on skills and competencies. In this approach, the teaching/learning process should accomplish both knowledge assimilation and skill development. Previous works demonstrated that a strategy that uses continuous evaluation is able to meet both objectives. However, those studies did not evaluate and quantify the additional effort required to implement such strategies. This paper evaluates the additional instructor effort required when implementing continuous evaluation in a first-year Computer Fundamentals course in the Computer Engineering degree program at the Technical University of Valencia, Spain. The experiment quantifies how instructor workload increases under different continuous evaluation strategies and how this affects the overall student grade. Both the "standard" continuous evaluation method and the intensive continuous evaluation method are analyzed, the latter being a proposal that builds upon the standard method by increasing the number of tests and examinations. The results obtained reveal that continuous evaluation improves student grades but that intensive continuous evaluation is liable to generate an excessive instructor overload without having a significant impact on student scores.

Abstract

[Resumen] En los entornos de movilidad, calles o carreteras, los cruces y las rotondas pueden generar problemas de atascos. Poder optimizar el tráfico entrante y saliente de un cruce o rotonda es uno de los campos de investigación de los sistemas de control inteligente. Para optimizar el tráfico se debe disponer de dispositivos capaces de detectar los vehículos así como de actuar, regulando el tráfico, de forma dinámica para adaptarse a las distintas circunstancias. El sistema presentado busca la adaptación a las necesidades de tráfico en una rotonda. Dependiendo de la saturación de cada carril de entrada se intenta crear un tráfico fluido y continuo en el interior de la misma. Para lograr mejorar el tráfico, en este trabajo se presenta una arquitectura modular que permite adaptarse a cualquier cruce o rotonda para, a partir del control específico de un sector, mejorar el rendimiento global. El sistema simulado está compuesto por dispositivos independientes, que, dependiendo de la información adquirida varían el tiempo de paso. Se presenta, asimismo, un experimento de simulaci ón en el que se pone en valor la capacidad de reducir el tráfico adaptando los tiempos de paso en función de la demanda. Los resultados muestran que es posible descongestionar una rotonda cuando se automatizan dinámicamente los tiempos de paso sobre los que se tiene control. [Abstract] Crossroads and roundabouts, can produce traffic jams if traffic management is not optimized. To manage these elements, it is necessary to have devices able to detect the level of traffic as well as to act dynamically in order to adapt the cross access time in each street. The system seeks to adapt to the traffic needs in the roundabout, depending on the saturation of each entrance lane, trying to create a fluid and continuous traffic inside it. In order to optimize the traffic, in this work, a simulation experiment is presented in which the ability to reduce traffic is valued by adapting the access times to a roundabout according to the traffic demand. The simulated system is composed of independent devices, which, depending on the information acquired, can change the access time to the roundabout. The results show that it is possible to reduce the traffic load in a roundabout when access times are dynamically automated. Ministerio de Ciencia e Innovación; TIN2017-86520- C3-1-R

Abstract

[EN] Object recognition, which can be used in processes such as reconstruction of the environment map or the intelligent navigation of vehicles, is a necessary task in smart city environments. In this paper, we propose an architecture that integrates heterogeneously distributed information to recognize objects in intelligent environments. The architecture is based on the IoT/Industry 4.0 model to interconnect the devices, which are called smart resources. Smart resources can process local sensor data and offer information to other devices as a service. These other devices can be located in the same operating range (the edge), in the same intranet (the fog), or on the Internet (the cloud). Smart resources must have an intelligent layer in order to be able to process the information. A system with two smart resources equipped with different image sensors is implemented to validate the architecture. Our experiments show that the integration of information increases the certainty in the recognition of objects by 2-4%. Consequently, in intelligent environments, it seems appropriate to provide the devices with not only intelligence, but also capabilities to collaborate closely with other devices., This research was funded by the Spanish Science and Innovation Ministry grant number MICINN: CICYT project PRECON-I4: "Predictable and dependable computer systems for Industry 4.0" TIN2017-86520-C3-1-R.
